calendar, almanac
暦 centers on a systematic record of days and seasons: a calendar or almanac used to track time and events.
暦 is the modern simplified form of 曆. The older form combines 日 (day) with 厤, which likely contributed the sound and the idea of passing through or arranging. The modern 厂 shape is a simplification of the upper part.
Under the cliff-like 厂, a tree 木 stands over the sun 日, marking the passage of days like a natural calendar.
For レキ, imagine a lake (レキ sounds like 'lake') with a calendar floating on it, each page marking a day.
